Pete, Thanks for the testing and taking the time to document it so well for us. And for the nice pics of such Busse-licious knives.
Re: firestarting in the wet, something we have here in the rainy NW USA as well.
One of the highest "bang for the buck" pieces of kit I've found, in terms of space efficiency, is Firestraws. For an item that weighs almost nothing and takes almost no space, they provide a surprisingly long-lived flame, serving as the tinder and first layer of kindling.
Firestraws are just short sections of plastic drinking straws
(fat ones from fast food joints can work well) stuffed with cotton ball material soaked with petrolium jelly (vaseline) which can be messy to handle, paraffin wax, or preferably beeswax. There are some comments on how much longer beeswax burns than paraffin wax
in this thread here.
If you do use petroleum jelly (PJ), you can squish it into the cotton balls (CB) by dropping the CB's into a ziplock bag, adding a dollop or two of PJ, zipping the bag shut, and kneading the contents together with the mess safely and conveniently confined to the inside of the bag. If you have more PJCB material than you need for a single firestraw stuffing session, you can simply store the unneeded PJCB material zipped up in the bag.
To make the firestraws, you pinch one end of a roughly 2" or so long section of plastic straw closed with a pair of pliers
(I like needlenose pliers) leaving a little of the plastic straw material exposed by the plier jaws. Then you melt the exposed plastic with a flame, sealing that end of the straw closed.
Next stuff in and pack your cotton soaked with vaseline or wax, filling half or more of the straw section, followed by enough dry (unsoaked) cotton ball material packed in to finish filling the straw section. To stuff in and pack tight the sometimes reluctant cotton material, you can use things like a Q-tip stick, ballpoint pen filler tube, the blunt end of a bamboo skewer as used for teriyaki, etc.
Then pinch & seal the open end of the straw section with a flame like you did the original end. Be sure that you have a waterproof seal, since if your firestraw leaks you may have trouble getting a spark to catch.
To use the firestraw, split the section of straw open
(slitting the side open works for me) and fluff out some of the uncoated cotton. Strike a spark into the fluffed cotton and bring it to a flame, which will melt some of the wax that then soaks into the cotton. You now effectively have a candle with the cotton fibers acting as mini-wicks. Eventually the plastic straw material will ignite and burn as well.
To add some more tenacity of flame endurance, you could insert a small strip or sliver of inner tube rubber into the straw section along with the coated and uncoated cotton. Once burning, rubber is very difficult to extinguish, even to the point of burning while soaking wet on occasion. Witness the tough time firemen have fighting junkyard tire fires.
